Our solar system's 'shocking' origin story

According to one longstanding theory, our Solar System's formation was triggered by a shock wave from an exploding supernova. It injected material from the exploding star into a neighboring cloud of dust and gas, causing it to collapse in on itself and form the Sun and its surrounding planets. New work offers fresh evidence supporting this theory, modeling the Solar System's formation beyond the initial cloud collapse and into the intermediate stages of star formation.
